TYPE-WRITING MACHINE.

SPECIFICATION forming part of Letters Patent No. 473,945, dated May 3,1892.

Application filed January 30, 1892. Serial No. 419,767. (No model.)

To all whom it may concern.-

Be it known that I, MATTHIAS K. MORRIS, a citizen of the United States,residing at 1-101- lidays Cove, in the county of Hancock and State ofWest Virginia, have invented certain new and useful Improvements inType-VVriting Machines; and I do declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to theletters of reference marked thereon, which form a part of thisspecification.

This invention relates to type-writers or type-writing machines in whichthe typebar is separated from and adapted to be held in the hand andapplied to the machine, with which it co-operates at the proper point topermit the desired letter or character to print. The depression of thetype bar compresses a spring, which, upon its regaining itself after theelevation of the type-bar, moves the carriage over the paper-support adistance equal to the width or space of a letter or character throughthe intervention of arelatively-fixed rack-bar and a pawl mounted upon aframe, which is pivotally connected with the carriage, which moves overthe paper-sup port after the printing of each letter or character orafter the said pawl-carrying frame is actuated or depressed, either forpurposes of spacing between the Words or moving the carriage to bringthe letters or characters in proper relation on the paper.

The object of the invention is to increase the efficiency of this classof machines, first, by improving the machine proper and the adjunctsmounted thereon, and, second, by changing the form of the type-bearingsurfaces of the type-bar, making them curved outward, and providingguides onthe said type-bar which coact with a guide upon the carriage toinsure the correct position of the letter or character to be printed.

The improvement will be more particularly set forth hereinafter andnoted in the claims, and is illustrated in the accompanying drawings, inwhich- Figure 1 is a perspective view of a typewriting machine embodyingmy invention, the type-bar being shown in co-operative relation thereto.Fig. 2 is a longitudinal section of the machine. Fig. 3 is a transversesection showing the guide serving as a fastening means for the type.Fig. 4 is a detail view of a portion of the type-bar guide detached fromthe type-bar.

The base A of the machine is preferably rectangular, and is provided onits upper side, near each longitudinal edge, with rack-bars B, which aresupported at their ends in suitable standards O, and midway of itslongitudinal edges with the paper-support D, which extends parallel withthe rack-bars B. The rack-bars are of metal, the preferable form beingsquare in cross-section, the teeth or notches I) being on the upper sideto be easily accessible by the pawls E, which engage therewith and feedthe carriage over the papersupport.

The carriage is composed of side pieces F, which are constructed toembrace the rackbars at their lower ends and slide freely thereon andwhich are connected together by the cross-barf, which carries thepaper-holder G, the type-bar-carrying frame H, and the pawl carryingframe I.

The paper-holder G is secured at one end to the cross-barf and extendsparallel with and directly over the paper-support D a sufficientdistance to retain the paper in place upon the said support and preventthe same from slipping. In order that the paper may be more firmly heldbetween the support and the holder, the upper face of the said supportcurves upwardly between its edges. and the holder G is correspondinglycurved, so that the paper is compressed between the two parallel curvedsurfaces. The opening (Z near the free end of the holder exposes thepaper beneath to receive the imprint of the letter or character in theoperation of the machine. The vertical guide J, secured to the holder G,co-operates with the guide K on the type-bar L and directs the letter orcharacter to be printed to the opening d in the holder G. Under normalconditions the holder G presses slightly on the paper, so that thecarriage can be moved easily over the paper without being impeded in itsmovements by undue friction. However, provisions are had to press theholder on the paper with more than usual firn1- ness on the applicationof the type-bar to the frame H, whereby the friction between the holderG and the paper on the support D will be increased to such a degree asto prevent the accidental slipping of the carriage when depressing theframe H and the type-bar. To

' this end the spring M is provided and attached When the type-bar iselevated, the spring M will regain itself and elevate the free end ofthe frame H and relieve the holder G of the extra pressure.

The frame H is open and one end is secured to or provided with therock-shaft m, which is journaled in the side pieces F, and which isprovided midway of its ends with a clip 71, the free ends of whichextend vertically and are slotted to receive the spring M, which extendsthrough the slots in the said clip. The outer end of the frame H isturned up,as shown at h, to form a rest for the type-bar L when placedon the frame H. The type-bar L is further supported by the platforms 77/one on each side bar of the frame H, which are padded to prevent injuryto the type carried by the said type-bar. The ink-roller N is supportedon the bent-up end h of the frame H and is inclined to admit of theconvenient inking of the type on the type-bar by passing the latter overthe said roller. The platforms 72. are sufficiently long to give a broadpurchase to the type-bar, thereby preventing injury to the type, and aredipped toward the longitudinal center of the frame to conform to thecurved outline of the type-bar, so that the latter may maintain auniform bearing on the said platforms 72.

The pawl-carrying frame is composed of a cross-bar 0, having the pawls Esecured to its outer ends and a bar P parallel with said rockshaft m,and secured thereto by the arms 19. The end of the spring M bears on thebar P, and the pawls have pivotal connection with the said bar P and canbe thrown up out of engagement with the rack-bars B at any time. Ondepressing the bent end of the frame H the bar P will be correspondinglyelevated, causing the pavils to advance the distance of one tooth ornotch on the rack-bars, and when the bent end of the said frame H iselevated the bar P is lowered, and the pawls engaging with the saidtooth or notch push the carriage forward the distance of said notch ortooth.

The type-bar is curved outward between its ends and is preferably flat,the curved edges forming faces or beds for the type, the latter beingpreferably of rubber. The capital letters are provided on one edge orface of the type-bar and the small letters upon the other. The side ofthe bar is provided with a suitable index Z, contiguous to thetype-faces, and the letters and characters upon the index correspondwith the letters and characters on the type-bar. The guide Q, projectinglaterally from the type-bar, is notched, the notches coming opposite thetype or characters on the index and adapted to co-operate with the guideJ to give proper position to the character to be printed on the paper.This guide Qextends across the typeface of the type-bar, and is flangedat q to extend up and be secured to the side of the type-bar. Theopenings q permit the projection of the type through the guide Q. Thelatter serves to retain the type in place and strengthens the type-barin the event of the latter being made of Wood.

What I claim to be new, and desire to secure by Letters Patent, is

1. In a type-writer of the character described, the combination, withthe base, the rack-bars, and the paper-support mounted on the base, of acarriage mounted on the rackbars, means for moving the carriage over thesaid base, a paper-holder secured to the carriage, a type-bar-supportingframe pivotally connected with the carriage, and a spring adapted to becompressed on depressing the said type-bar-carrying frame and press thesaid paper-holder more closely upon the paper-support, substantially asand for the purpose set forth.

2. In a type-writer of the character de-- scribed, the combination, withthe paper-support and a carriage adapted to be moved over the saidpaper-support, of a type-barsupporting frame having pivotal connectionwith the carriage and having a rest It and platforms b at its free end,said platforms being dipped toward the center of the said frame,substantially as and for the purpose described.

3. The combination, with the base having rack-bars and a paper-support,of a carriage consisting of side pieces F, which are mounted on therackbars, and a cross-bar f, connecting the said side pieces, apaper-holder proj ected from the cross-bar f, a type-bar-carrying framepivotally connected with said side pieces F by rock-shaft m, abar P,secured by arms 19 to the bar on and having pawls 0 pivotally connectedtherewith, said pawls being adapted to engage with the rack-bars, andspring M, secured between its ends to the rock-shaft m and adapted tohave its ends engaged, respectively, with the bar P and the saidpaper-holder, substantially as set forth and described.

In testimony whereof I afiix my signature in presence of two witnesses.
